To calculate the mass of a given number of moles of a substance, it is important to determine the molar mass of the substance. For CaCO3, the molar mass is equal to 100.09 g / mol. We calculate as follows:
5.66 mol CaCO3 ( 100.09 g / mol ) = 566.51 grams of CaCO3
It has 8 valence electrons because the charge is -2.
